1. A laminated glazing pane comprising:
a first sheet of glazing material having a first major surface and a second opposing major surface,
a second sheet of glazing material having a first major surface and a second opposing major surface,
an interlayer structure joining the first sheet of glazing material to the second sheet of glazing material, the interlayer structure comprising at least one sheet of adhesive interlayer material, and
an illumination device comprising one or more light source,
wherein the laminated glazing is configured such that
the interlayer structure is between the first and second sheets of glazing material;
the second major surface of the first sheet of glazing material faces the first major surface of the second sheet of glazing material; and
the illumination device is arranged relative to the first sheet of glazing material to emit light towards the second major surface of the first sheet of glazing material;
wherein the first and/or second major surface of the first sheet of glazing material has an array of dots thereon, each dot having a size,
wherein the size of each dot and the spacing thereof in the array of dots is selected to provide a diffusing function to light emitted by the one or more light source by blocking some of the light that is emitted by the illumination device thereby diffusing light emitted by the illumination device that is transmitted through the first sheet of glazing material and out from the first major surface thereof.
